Memory management is one of the most important process in any programming language. It is the process by which the memory of objects are allocated when they are required and deallocated when they are no longer required. Managing object memory is a ma…

Open Cascade中的内存管理 Memory Management in Open Cascade eryar@163.com 一.C++中的内存管理 Memory Management in C++ 1. 引言 为了表现出多态,在C++中就会用到大量的指针和引用.指针所指的对象是从内存空间中借来的,当然要及时归还.特别是指针在程序中随心所欲地创建,因此,一个指针究竟指向哪个对象,一个对象到底被几个指针所指向,是程序员十分关注的事情. C++中涉及到的内存管理问题可以归结为两方面:正确地掌…

Objective-C Memory Management Using Reference Counting 每一个从NSObject派生的对象都继承了对应的内存管理的行为.这些类的内部存在一个称为retain count的计数器.使用对应的调用,这个计数器会做自增或者自减.Objective-C runtime知道这个计数器何时变为0,此时会做deallocated.当对应deallocated时,它所占用的所有memory都会被释放.有三种方法可以让retain count增加: 当你使用含…

Understanding Memory Management Memory management is the process of allocating new objects and removing unused objects to make space for those new object allocations. This section presents some basic memory management concepts and explains the basics…

Java Memory Management, with its built-in garbage collection, is one of the language’s finest achievements. It allows developers to create new objects without worrying explicitly about memory allocation and deallocation, because the garbage collector…
